how to use of GUI?

for example I have a matrix X. lets say

X=rand(10)

then I wrote something like this as GUI

function [] = Mohammad() 
M = figure('units','pixels',...
              'position',[500 500 200 50],...
              'menubar','none',...
              'numbertitle','off',...
              'name','Mohammad',...
              'resize','on')
  whitebg(M,'r')
  set(M,'Position',[500 500 400 300])
   m = uimenu('Label','&File');
  uimenu(m,'Label','Open','Callback',{@fm});
  uimenu(m,'Label','Quit','Callback','close',...
    'Separator','on','Accelerator','Q');

function [] = fm(varargin)
    % Callback for the figure menu.
       [filename, pathname] = uigetfile({'*.mat', 'All MAT-Files (*.mat)';'*.*','All Files (*.*)'},'Open file');
end
end

right now, I want while I am loading the data by the "open" from my GUI, it calculates correlation coefficient by following command >> [r]=corrcoef(X)

and give me the result

do you know how should I revise the GUI?

First you have to create *.mat file:

X = rand(10);
save Xvar X

And possible solution:

function [] = Mohammad() 
M = figure('units','pixels',...
            'position',[500 500 200 50],...
            'menubar','none',...
            'numbertitle','off',...
            'name','Mohammad',...
            'resize','on');
whitebg(M,'r')
set(M,'Position',[500 500 400 300])
 m = uimenu('Label','&File');
uimenu(m,'Label','Open','Callback',{@fm});
uimenu(m,'Label','Quit','Callback','close',...
  'Separator','on','Accelerator','Q');

function [] = fm(varargin)
  % Callback for the figure menu.
     [filename, pathname] = uigetfile({'*.mat', 'All MAT-Files (*.mat)';'*.*','All Files (*.*)'},'Open file');
     r = load(fullfile(pathname,filename));
     disp(corrcoef(r.X))
end
end

Thanks

I have another question if I would like to only load the data by "open" and put a bottom for the correlation coefficient , then what should I do ?

[Grzegorz Knor]

You mean something like this?

function [] = Mohammad()

M = figure('units','pixels',...

'position',[500 500 200 50],...

'menubar','none',...

'numbertitle','off',...

'name','Mohammad',...

'resize','on');

whitebg(M,'r')

set(M,'Position',[500 500 400 300])

m = uimenu('Label','&File');

uimenu(m,'Label','Open','Callback',{@fm});

uimenu(m,'Label','Quit','Callback','close',...

'Separator','on','Accelerator','Q');

h = uicontrol('Style','text','Units','normalized','Position',[.0 .25 1 .5],'BackGroundColor','r');

function [] = fm(varargin)

% Callback for the figure menu.

[filename, pathname] = uigetfile({'*.mat', 'All MAT-Files (*.mat)';'*.*','All Files (*.*)'},'Open file');

r = load(fullfile(pathname,filename));

set(h,'String',num2str(corrcoef(r.X)),'FontSize',5)

end

end

No, I wanted to put a bottom on the window for example "CC",

then I load the data by "open" and when I push the "CC" it calculates the correlation coefficient

You mean button?:)

function [] = Mohammad() 
M = figure('units','pixels',...
            'position',[500 500 200 50],...
            'menubar','none',...
            'numbertitle','off',...
            'name','Mohammad',...
            'resize','on');
whitebg(M,'r')
set(M,'Position',[500 500 400 300])
 m = uimenu('Label','&File');
uimenu(m,'Label','Open','Callback',{@fm});
uimenu(m,'Label','Quit','Callback','close',...
  'Separator','on','Accelerator','Q');
h = uicontrol('Style','pushbutton','Units','normalized','Position',[.4 .45 .2 .1],'String','CC','Callback',@fm);
function [] = fm(varargin)
  % Callback for the figure menu.
     [filename, pathname] = uigetfile({'*.mat', 'All MAT-Files (*.mat)';'*.*','All Files (*.*)'},'Open file');
     r = load(fullfile(pathname,filename));
     disp(corrcoef(r.X))
end
end

I recommend you familiarize yourself with these examples:

Thanks, In fact I went through all of them ,

It was not what I wanted,

Ok you put a bottom but all what I wanted was ,

using the "Open " to load the data

and program wait until I push on the bottom , then calculate it , it was all what I wanted
